WOOD TURNiNG MACHlNE.

SPECIFICATION forming part of Letters Patent No. 696,824, dated April 1,1902.

Application filed July 26, 1901. Serial No. 69,791. (No model.)

To all whom, it nmy concern:

Be it known that I,WILLIAM THOMAS J ONES, a subject of the King of GreatBritain, residing at New WVestminster, in the Province of BritishColumbia and Dominion of Canada, have invented a new and Improved Vood-Turning Machine, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in wood-turning machines, andparticularly for turning spools'or similar small articles; and

the object is to provide a machine practically automatic in itsoperation and by means of which a plurality of spool-blocks arranged inaxial line may be simultaneously acted upon and finally ejected asfinished spools. Other objects of the invention will appear in thegeneral description.

I will describe a wood-turning machine embodying my invention, and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a top plan view of a wood-turning machine embodying myinvention. Fig. 2 is a side elevation thereof. Fig. 3 is an end view ofthe same. Fig. 4 is a detail showing means for swinging and operating agang of saws. Fig. 5 is a sectional detail showing block-carriers andmeans for moving them to and from boring-tools. Fig. 6 is an edge viewthereof. moving mechanism employed. Fig. 8 is a section substantially onthe line or m of Fig. 1. Fig. 9 shows one of the knives employed. Fig.10 is a plan view of a bloclefeeding mechanism employed, and Fig. 11 isa rear elevation thereof.

The frame of the machine comprises end uprights 1, connected by end bars2 and side bars 3. l/lounted in the forward portion of the machine andhaving bearings in the frame is a main driving-shaft 4,.on one end ofwhich at the outer side of the frame is a fixed driving-pulley 5 and aloose pulley 6. On the opposite end of the shaft 4 and at the outer sideof the frame are step-pulleys 7 and 8. Also mounted on thisdriving-shaft are drivingpulleys 9 and 10 for operating the bands whichFig. 7 is a detail showing a block-,

impart movement to the spool-carrying spindles,as will be hereinafterdescribed; and also fixed to the shaft (here shown at one side of thepulley 10) is a pulley 11 for operating one of theboring devices, and apulley 12 on the shaft is designed to operate a gang of saws.

A gang of saws (here shown as two saws 13 and 14) is mounted on aspindle having bearings in a swinging frame comprising uprights 15.These uprights are connected by a crossbar 16, and the lower portions ofsaid uprights are mounted to swing on the driving-shaft 4, as clearlyillustrated in Figs. 2, 3, and at. On the spindle of the saws is apulley 17, from which a band 18 extends to the pulley 12. It will benoted that one of the saws is of larger diameter than the other-that is,the saw farthest from the point in which the stick of wood from whichthe blocks are cutis of the larger diameter. The object of this is tocut off the farthest stick before the inner one is cut 0d,

so asto provide a bearing temporarily to prevent the inner block oreither of the blocks from being moved forward to the cutting devicebefore the said inner block shall have been entirely severed from thestick.

A forward-and-back motion is imparted to the saw-carrying frame by meansof an cecentric cam 19, mounted on a cam-shaft 20.

This eccentric cam engages the walls of a cam-strap 21, which ispivotally connected at its lower end to a bracket 22, extendedfrom across-bar 23 of the machine-frame. From the upper portion of thiscam-strap a rod 24 extends to a lever 25, connected at its lower end toa rock-shaft 26, having hearings in blocks 27, arranged at one end ofthe machine. Also having pivotal connection with this rock-shaft is apitman 28, which extends forward and connects with the swinging carrierof the saws. .By the construction of the eccentric and eccentric-ringthe saws will be given a much quicker return or back'moveinent than themovement in the cutting di rection, thus freeing the blocks of wood forsubsequent operation.

Arranged along the top of the machine and adapted to receive blocks ofwood from the saws is a guide-platform 29, upon the sides of which areaffixed standards 30, having lon-- gitudinal rails 31 at the top, whichprovide side rails 32. These rods 36, extend ed. through slots in theloop portions 35 of opposite hangers, are shown as screw-rods, so thatthe fingers and the hangers may be adjusted laterally and vertically.There will be a series of these fingers at each side of the center ofthe machine, so as to engage the blocks severed by the two saws.

A back-and-forth motion is imparted to the finger-carriage by means of aheart-cam 37, mounted on the cam-shaft 20. An operatingbar 38 is mountedon a roller 39, which engages in the channel of the cam 37, and the endof said bar is provided with a slot through which the shaft 20 may pass,permitting the said bar to move longitudinally relatively to the shaft.The opposite end of this bar 38 is connected to alever 40, extendedupward from a rock-shaft 41, and also extended upward from thisrock-shaft 41 is a lever 42, which has a link or rod connection 43 withthe finger-carriage.

Movable transversely in the guide plate or table 29 are block-carriers44 and 45 for moving the blocks to be bored to and from theboring-angers 46 and 47. These carriers 44 and 45 have their edgesbeveled in opposite directions and engaging in correspondinglyshapedchannels formed in the plate 29, as clearly indicated in Figs. 6 and 7.Mounted on each carrier 44 45 is an inner stop-lug 48 and an outerstop-lug 49. These stop-lugs are designed to engage against the ends ofthe blocks to cause their movements with the carriers. The lugs 49 areshown as adjustable toward and from the lugs 48, so as to accommodatethe carriers to different lengths of blocks, and they may be held asadjusted by means of set-screws.

Outward and inward movement is imparted rally-disposed channel 53, inwhich a roller or block 54, depending from the carrier 45, extends.These spiral channels are arranged in opposite directions, so that thetwo carriers will be simultaneously moved toward or from each other.

The boring-tool 46 has a chuck connection with a spindle 55, on which isa pulley 56, from which a band 57 extends to a connection with a pulley58, mounted on a short shaft or stud 59. Also on this short shaft orstud 59 is a pulley 60, with which a band 61, driven by the pulley 9,engages. This band 61, as willhereinafter appear, operates one set ofthe spool or block carrying spindles.

The boring-tool 47 has a chuck connection with a shaft onwhich is apulley 62, from which a band extends to the pulley 11 on thedriving-shaft. By this arrangement it is obvio us that the twoboring-tools will be rotated in opposite directions.

Mounted in the frame is a reel-carrying shaft 63, on which is affixed acenter spider 64, and at one side of the center spider is a spider and aspider 66. The spider 65 is designed to support the inner ends ofspindles, while the spider 66 is designed to support the body or outerportion of said spin dles. Also connected to the shaft at the oppositeside of the center spider is an inner supporting-spider 67 and an outersupportingspider 68. Mounted to rotate in bearings formed in the innerand outer spiders is a series of spool or block engaging spindles 69,one of which is shown in detail in Fig. 8. In the bearings of the outerspiders are brass bushings 70, in which the spindles may rotate and movelongitudinally, and the brass bearings 71, supported by the innerspiders, are designed to permit the rotary and longitudinal movements ofthe spindles; but the inner ends of these bushings or bearings 71 areprovided with small openings 72, through which the reduced stems 73 ofthe spindles may pass, these reduced stems being designed to enter thebored holes in the blocks. The ends of these portions 73 are stillfurther reduced, as at 74, to enter openings formed in the periphery ofthe center spider 64. Of course the bearings and the openings of thecenter spider will be arranged in axial line.

As a means for trimming off the bur around the ends of the holes in theblocks I provide on the ends of the bushings or bearings 71 smallcutters 75, while similar cutters 76 are arranged at the opposite endsof the hearings in the center spider.

On each of the spindles carried by the spiders 65 and 66 is a pulley 77,designed to be engaged by a belt or band driven by the pulley 10 andsimilar to the belt or band 61, driven by the pulley 9. The belt or band61, driven by the pulley 9, is designed to engage with pulleys 78,attached to the spindles carried by the spiders 67 and 68. The saidspindle-driving bands pass over idlers 79, mounted on a shaft 80 at thefront end of the machine, and are engaged by pressure-rollers 81 to takeup the slack. These pressure-rollers 81 are mounted on arms82, mountedto swing on a bar 83, supported by upright-s of the machine.

Attached to the frame of the machine is a cutter-carrying plate 84. Thisis shown as segmental in form and concentric with the reel-carryingshaft. Mounted on this plate 84 is a series of cutters 85, which aresuccessively arranged from the upper end to the lower end to cutgradually deeper into the wood, the last cutter of the series finishingthe spools. Each cutter is designed to operate upon a plurality ofblocks. I have here shown them (in Fig. 10) for operating upon twoblocks, thus forming two spools at once. The cutters 85 are mounted onshanks 86, adjustable in blocks 87 on the plate 8%. As here shown, theseblocks 87 have channels the opposite walls of which are undercut toengage the corresponding edges of the shanks 86. The cutters may beheldas adjusted by means of set-bolts 88, operating in the blocks andengaging against the shanks. The cutters may be adjusted as to theirangle with relation to the spool-blocks by swinging the blocks 87 Theseblocks 87 are shown as pivotally connected, as at 88, to the plate 84,and from the blocks 87 near the outer ends lugs extend through arc slotsin the plate 8%, and these lugs maybe engaged byfastening-nuts to holdthe blocks as adjusted angularly.

Attached to the side rails of the frame and extending upward therefromare presser plates 89, portions 90 of the front of which are inclineddownward and outward. These presser-plates are designed to engage withthe outer ends of the spindles for forcing them into the blocks. Theinclined portions 90 will gradually force the spindles in, and extendeddownward in acurved line from the rear ends of the straight portions ofthe presser-plates 89 are cams 91, designed to withdraw the spindlesfrom the blocks. 1 These earns 91 are shown as inclined from the centerof the machine outward, and their free ends are in the entrance end ofthe presser-plates and securedto the machine-frame are springs 94, whichare designed when the spindles are passing the holes in the bored-blanksor blocks to force the said spindles quickly into the holes and pick upthe blanks on the spurs.

On the inner end of the block chute or carrier 29 and at opposite sidesare steel blocks 95, which are designed to be adjusted so that the topedges will be just below the bottom of the holes in the oppositespool-blanks, and

two blocks as they approachthespindles, and the blocks'are held untilengaged by the spindles by means of spring-fingers 97, attached to thechute orplate 29.

Mounted on the reel-shaft 63 is a loose pulley 98, to one side of whichis attached apinion 99, which of course is also loose on-the shaft 63.This pinion 99 meshes with a gearwheel 100, mounted ona stud 101,extended from one side of the machine-frame, and at tached to thisgear-wheel 100 is 'a pinion 102, and this pinion 102 meshes with agear-wheel 103, attached to the reel-shaft 63. By this means motion isimparted to the reel from .the pulley 98. Directly below the pulley 98and connected therewith bya band104 is a pulley 105, on the shaft ofwhich is a steppulley 106, from a step of which a band 107 extends tothe step-pulley7 or 8 on the driving-shaft', depending upon the rate ofspeed desired. The band 104. is slack and maybe tightened at thepleasure of the operator by means of an idler-pulley 108, engaging withsaid band, the said idler-pulley being mounted on alever 109, on theupper end of which is ad justably arranged a weight 110. This lever 109is mounted to swing on a boss extended from one side of themachine-frame, and it may be thrown back against the flanged pulley onthe reel-shaft, when the belt will be too slack to give motion to thereel, or it may be thrown down, so that the pulley on the end of thelever will take up the slack of the belt by the weight overbalancing thepulley, and thus motion will be imparted to the reel.

Mounted on the same stud on which the lever 109 is fulcrumed is a pinion111, which meshes with the gear-wheel 103, and connected to this pinion111 is a gear-wheel112, meshing witha pinion 113 on the cam-shaft 20,and by this means the said cam-shaft is rotated. The pinion 111 hastwenty teeth and the gearwheel103 has one hundred and twenty teeth or aratio of six to one. The wheel 112 has forty teeth, while the pinion 113has twenty teeth. This gives the cam-shaft twelve revolutions for one ofthe reel-shaft or one revolution for each spindle carried by the reel.

It may be here stated that the saws are adjustable toward and from eachother, that the sides of the block chute or table are adjustable towardand from each other, and that different widths of cutting-knives may beemployed, thus permitting the machine to be adapted for differentlengths of work to be'operated upon. p

In operation the attendant places the strip of wood upon thefeeding-table 114c and pushes it up against a side of the block-chuteand of course in the line of movement of, the saws. The saw-carriagetheumoves forward and the saws cutoff two blocks, the onenext the stopbeing the first severed by the largersaw. The camthen causes thefinger-frame to push forward the severed blocks half-way to thetransverseblock-carriages. The operatorhas in the meantime pushedthestrip against the stop again and twomore blocks are severed. The secondfingers in the finger-frame ride upon the first blocks and drop downbehind them as the finger-frame recedes. As the finger-frame advancesagain the first blocks are transferred to the block-carriages. The camfor operating said block-carriages moves them outward to push themagainst the boring-tools, and of course the boring-tools are then thrownout by the operation of the carriages-that is, by the inward movement ofthe carriages. These operations are repeated until two bored blocks areopposite the spurs on the reels. These each pick up a spool-blank. Thespurs are pushed through the blanks until the ends of the spurs rest'inthe bearings of the center spider. As the reel revolves the pulleys onthe spindle come in contact with the belts on the main shaft of themachine, thus imparting a rapid rotary motion to the spindles andspool-blanks, and as the reel continues its revolution the spoolblankscome in contact with the cutters, each one of which has a part assignedto it.

When the spindles have passed thelast cutters, the spools are finished,and the returncams engage the collars on the ends of the spindles, sothat the spindles are withdrawn, and the finished spools drop off. Thisoperation goes on continuously, each spindle taking up its spool-blankin turn.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
